Product details
These easy to use, intrinsically safe tachometers can display speed in engineering units from a wide variety of pulse output sensors such as a proximity detector or switch contact. To simplify maintenance, the instruments also contain a second display which can simultaneously show the run-time of the monitored machinery. International certification allows worldwide installation.

Accessories, include a display backlight, isolated dual alarms, isolated 4/20mA output for BA317E and BA317E-SS and isolated synchronous pulse output.

Tachometers can be supplied configured and fitted with a customer specified printed scale card showing the units of measurement for no additional charge. Specified tag or application information can also be printed onto the rear of the instrument.
